Your file never leaves your browser

How to Flatten a PDF

  • Upload a PDF that has fillable form fields, with the fields already filled in as needed.
  • Click Flatten PDF — the filled-in values are merged into the page content.
  • Download the flattened PDF, where the form fields are no longer editable.

Example

A filled-out application form with text fields and checkboxes, once flattened, looks identical but the fields can no longer be edited or tabbed through — the entered values become permanent page content.

Common Use Cases

  • Locking a filled-out form before sending it, so recipients can't accidentally change answers.
  • Preparing a form for archival where the values shouldn't be editable.

FAQ

  • What if my PDF has no form fields? There's nothing to flatten — the tool will tell you no fields were found.
  • Is my file uploaded anywhere? No — flattening happens entirely in your browser.
